Please, keep the mail within the maillist thread.

No, it doesn't add too much load to Kamailio. This is one of the major
purposes of a transaction stateful proxy (the serial forking in order
to implement failover).
Take a look to the LCR module. It gives you load balancing (with
priorities if you want) and failover features. It's all you need in
your scenario.
